We divide 750804 by 3
The aim is to understand the frequency of 3 in 750804.

Let's proceed to step 1:
3 goes into 7 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 1 after subtracting 6 from 7.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Going ahead to step 2:
3 can be fit into 15 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 15 from 15 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Step 3:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 250.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Let's proceed to step 4:
When dividing 8 by 3, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2502.0
If we take 6 away from 8, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Step 5:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 25026.0
Deduct 18 from 20 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 3

Advancing to step 6:
24 divided by 3 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 250268.0
If we subtract 24 from 24, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 250268.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 250268.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 250268.0 with a remainder of 0.0.
